That sounds about right, but please check your naming very carefully. If you are using normal Rails conventions, then your relationships would look like this class Bar < ActiveRecord::Base has_many :details has_many :locations, :through => :details end etc. Always name the class Singular, Upper Case, CamelCased and always refer to the plural relationship the same as the table name -- plural, lower-case, and under_scored.
